Frown lines around the mouth: causes and options

The mouth moves frequently for speaking, eating, smiling, and pursing the lips. Repeated folding can leave vertical or curved creases around the lip border and corners. Dryness and ultraviolet exposure can make the surface look more lined, while changes in collagen, facial volume, or tooth support can alter how shadows fall around the mouth. These features are part of the broader group of [Wrinkles](/symptoms/wrinkles/).

The phrase frown lines around the mouth can describe different patterns, so location matters. Lines above the upper lip are not managed in exactly the same way as downturning lines at the corners. An examination helps separate movement from texture and structural change.

Apply sunscreen to the face and use a bland moisturiser to support the skin barrier. Avoid licking the lips, smoking, and irritating scrubs, all of which can worsen dryness or repeated folding. A topical retinoid may improve fine texture gradually, but it can cause irritation and needs individual guidance.

Depending on the pattern, a dermatologist may discuss Botox to reduce selected muscle activity or dermal fillers to restore carefully assessed support. Around the mouth, small changes can affect speech, smiling, and eating, so treatment requires conservative planning and an experienced medical injector. See [Botox](/treatments/injectables/botulinum-toxin-injection/) and [Dermal Fillers](/treatments/injectables/dermal-fillers/).

Seek urgent care for sudden facial drooping, weakness, numbness, trouble speaking, or vision changes. Have a clinician examine a sore, crust, bleeding area, or changing spot around the mouth. After an injection, promptly report escalating pain, pale or dusky skin, unusual coolness, spreading redness, marked swelling, or visual symptoms.

Ask which pattern you have, whether skincare alone is reasonable, how an option could affect movement and expression, what recovery involves, and which post-treatment changes need urgent assessment.
